One of the main obstacles to such tissue engineering has been producing the network of tiny blood vessels that keep newly growing natural tissue alive. (sciencemag.org)
«To date, there has been no systematic means of assessing the fidelity of cellular engineering — to determine how closely cells made in a petri dish approximate natural tissues in the body,» says George Q. Daley, MD, PhD, Director of the Stem Cell Transplantation Program at Boston Children's and senior investigator on both studies. (sciencedaily.com)
Of the numerous stages to go through before this method gets to the clinic, not least is the need to confirm the degree of integration of the scaffold within natural tissue in the brain, he says. (newscientist.com)
